nupnovnn CURTAIN-FIXTURE.

The Schedule referred to in these Letters Patent and making part thesama.

To all whom. it may concern.- v

Be it known that I, MosEs S. MARSHALL, of Somerville, lcounty ofMiddlesex, and State of Massachusetts, have invented lcertainImprovements in Curtain-Fixtures, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, making part of this specification, in'\vhich- Figure 1represents a Icomplete fixture, with a curtain wonnd upon the case,which is held in brackets attached to a window-frame.

`Figure 2 is a longitudinal sectional view. of the complete fixture. v

Figure 3 shows a spindle, which runs through the case, and upon which iswound a spring attached to spindle latl? and head-,piece I.

Figures 4 and 5 show my specific improvements.

My invention relates to that classof-curtain-Jixtures where the weightis dispensed with, and the curtain rolled up by theaction of a spring.But the objections which arise in operating a ixture of this kind, andin removing it from its brackets, as well as the constant wearing out oftape, which is. used in some, and the inconvenience which is occasionedby the-liability of the spring to unwind when. the fixture is beingremoved from the brackets, have led to my invention.

My object is to overcome the ordinary difficulties, and todo so, I use alatch and pawl combined, which hold the spring from unwinding, andkeepthe curtain at any4 height.

In the drawings- A is a hollow casing of wood, or any suitable material,and upon which the curtainl is fastened by ordinary methods.

D is a spindle, upon which is wound the spring U, the spring and spindlebeing placed within the casing A.

'7c is a crooked latch, secured to one side of the spindle D. k is shownin iigs. 4 and 5.

e is a pawl, having a catch-point, m.

The pawl is fastened to the end of casing A, at screw g. l

The pawl e has a lip, c, thrown out to one side, which lruns close tothe spindle D when the casing is revolving, and prevents the pawl fromfalling completely over, and by the lip c being thrown -to one side, asshown, the crooked latch kis allowed to clear it without being impeded.l

Now, to operate the future, the spring C must be wound up, by means ofturning the spindle D at a, at'.

the same time the curtain isA rolled upon case A.

The fixture is then placed in brackets'L, the spindle D being held inposition, by means of theA projecting end being dat, as shown 'at b, andthe slot o, in the bracket on that side, being made to hold the'spindle,

to bring theflatch lo upon the upper side.

The spindle is held down by pin p.

H is-a cord attached to the curtain, for conveniently operating it.

llVhen` the curtain, by the cord, -is-drawndown, the movement brings thelatch k against the pawl e, thereby throwing the pawl up, but not over,as the lip c runs against .the spindle D and prevents. Therefore, thereis no obstruction to drawing the curtain down to its full length.

To let the curtain back, that is, to roll it up again, draw the cordv Hsufficiently to disen gage thepawl from v the latch, and then let thecurtain up quickly, when the centrifugal motion thus given the pawlprevents inl-:esame from engaging withdatch k,"and,' by meansl vof lipc, is also prevented from being thrown overl To keep the curtain at anydesiredheight, all that is p case is turned one-quarter round againstthe spring.

Thus I secure-the spring in a rm position, without liability to unwind,either in removing the xture from the brackets, or in operating it, andthe curtain is coni trolled at any point without weights, and withoutusing tape, which wears out ina sgort time.

I disclaim the `use of thecase A, spring O, and spindle D, as described,asthey are old, and embodied in other patents. What I claim as myinvention, and desire to secure by Letters Patent, isy Thecoinbinationof pawl e with catchm, crooked latch 7c, which is secured tospindle D, atb, and lip c,

when applied to regulating .and operating a curtain-fix- 'y ture, asdescribed and specied.

In. testimony whereof, I have signed my name to this speci'dcation, inthe presence of two subscribing wit- MOSES S. MARSHALL. Witnesses:
